place(optional)Captures the placement of the item with respect to the staff with which it is associated. Value conforms to data.STAFFREL.
(MEI.shared) Visual offset attributes. Some items may have their location recorded in terms of offsets from their programmatically-determined location. The ho attribute records the horizontal offset while vo records the vertical. The to attribute holds a timestamp offset, the most common use of which is as an alternative to the ho attribute.
(MEI.shared) Horizontal offset attributes.

(MEI.shared) Visual offset attributes. Some items may have their location recorded in terms of pairs of offsets from their programmatically-determined location. The startho and endho attributes record the horizontal offsets of the start and end points of the item, respectively. Similarly, the startvo and endvo attributes record the vertical offsets of the start and end points of the item. The startto and endto attributes hold timestamp offsets, the most common use of which is as alternatives to the ho attributes.

(MEI.shared) Output coordinate attributes. Some elements may have their exact rendered *output* coordinates recorded. x and y attributes indicate where to place the rendered output. Recording the coordinates of a feature in a facsimile requires the use of the facs attribute.
x(optional)Encodes an x coordinate for a feature in an output coordinate system. When it is necessary to record the placement of a feature in a facsimile image, use the facs attribute. Value is a decimal number.
y(optional)Encodes a y coordinate for a feature in an output coordinate system. When it is necessary to record the placement of a feature in a facsimile image, use the facs attribute. Value is a decimal number.

y2(optional)Encodes the optional 2nd y coordinate. Value is a decimal number.
